The Soosan Hydraulic Breaker will provide safe and dependable service if operated in accordance with the instructions given
in this manual. Read and understand this manual, any decals and tags attached to the breaker before operation. Failure to do
so could result in personal injury or equipment damage
• Operate the breaker in accordance with all laws and regulations which affect you, your equipment, and the worksite.
• Do not operate the breaker until you have read this manual and thoroughly understood all safety, operation and
maintenance instructions.
• Do not operate the breaker until you have read the carrier equipment manual and thoroughly understood backhoe or
excavator or similar equipment used to operate the breaker. The word "carrier", as used in this manual, means a backhoe
or excavator or similar equipment used to operate the breaker.
• Ensure that all maintenance procedures recommended in this manual are completed before using the equipment.
• The operator must not operate the breaker or carrier if any people are within the area where they may be injured by flying
debris or movement of the equipment.
• Know the limits of your equipment.
• Before starting a work, Check the prohibitions, cautions and working processes in a working site with the field overseer,
Observe all of them strictly.
• Wear such protective tools as a helmet, safety shoes, etc. to perform a work.
Make use of the protective glasses, earplugs, gloves and other protective tools if necessary.
• Establish a training program for all operators to ensure safe operation. Do not operate the breaker unless thoroughly trained
or under the supervision of an instructor. Become familiar with the carrier controls before operating carrier and breaker. While
learning operate the breaker and carrier, do so at a slow pace. If necessary, set the carrier to the slow position.

1) Use ear protection 2) Use eye protection
3) Use breathing protection 4) Read the manual before use
• Greasing Sticker
Correct Greasing
1) Position the Breaker standing upright resting on the rod on firm surface.
2) Stop carrier engine and wait 10 minutes for oil pressure to drop inside Breaker.
3) Apply Rod grease from grease gun to greasing points marked with the following sticker.
Note : The Breaker must stand upright resting on the tool to ensure that the grease will penetrate
downwards between the tool and the bushing.
Do not fill the space between the piston and the rod with grease. A lower piston seal
failure can result and the Breaker will subsequently leak oil.

• Removal of the Hydraulic Breaker
When the bucket and breaker operate alternately, the bucket and breaker can be easily exchanged by the
hydraulic hoses and two mounting pins. However, there is a risk of hydraulic contamination accordingly.
Do installation and removal as follows.
(1) Move the carrier to stable ground, free from mud, dust and dirt.
(2) Place the hydraulic breaker on timber.
(3) Stop the engine, turn off the main switch and deflate air from oil tank if it is
(4) Turn 90° the shut off valve installed to the end of arm to prevent hydraulic from flowing out.
(5) Loosen the hose plug on the breaker arm. Collect a small amount of oil flowing out at this time and put into a container.
(6) Be careful to prevent mud or dust from entering oil hoses and pipe lines. Plug oil hoses with hose plug and pipe lines
with union caps. Bind high and low-pressure hoses with a wire to prevent them from getting on the ground.

05. Precautions for safe operation.
[1] Proper position must be applied for an effective usage of breaking force.
When position is incorrect, hammering energy of the piston is too weak to break rocks,
[2] On the contrary, when position is excessive enough to break rocks with front of the base machine raised, the machine
may suddenly tilt forward the moment rocks are broken. Then, the breaker body or the end of bracket may violently hit
against rocks and result in damage.
4.3 Hydraulic pipe lines for exclusive use
Operation of the hydraulic breaker requires installation of hydraulic pipe lines for exclusive use of the hydraulic breaker. As
hydraulic pipe lines vary depending on base machines, our service engineer must first check hydraulic pressure, oil capacity,
pressure loss and other conditions of the base machine before installing hydraulic pipe lines. Use only genuine parts in case of
replacement because hydraulic pipe lines (hoses, pipes and fittings) are made of materials carefully selected in consideration
of durability.
WARNING
THE HYDRAULIC SYSTEM TO THE BASE MACHINE MUST BE CHECKED BY AN AUTHORIZED SOOSAN SERVICE
ENGINEER BEFORE FIRST USE AND AFTER ANY MODIFICATIONS.
MAKE SURE THAT THE HYDRAULIC BREAKER VALVE OF HYDRAULIC SYSTEM IS PROPERLY SET.

[5] Do not use the breaker rod to move rocks. The stone claws are designed for this purposes.
[6] Do not use the breaker to sweep the ground of debris.
This may damage the breaker and the housing will wear out more quickly
[3] It is undesirable to carry out hammering under the below condition, because vibrations during hammering
may be transmitted to tracks of the base machine.
During hammering, however, proper position must be always applied to the breaker.
Special care must be taken not to hammer under abnormal condition.
[4] Apply same direction of boom force in line with the rod and place the rod in the rock with hammering surface as vertical
as possible. If hammering surface is oblique, the rod may slip during hammering. This causes the rod to seize and to be
broken and piston to be damaged. When breaking, fully stabilize the rod first and then select the point of a rock on which
hammering can be performed in a stable condition.

[9] Do not operate the breaker with the carrier's boom, stick or bucket cylinders at the end of
their stroke (either fully extended or fully retracted). Damage to the carrier may result
[10] Do not use the breaker or breaker rods for lifting.
Lifting eyes on the breaker are for storage and maintenance purposes only.
[11] Warm-up of machine prior to operation
- Do not operate the machine right after starting the engine. Idle the machine for warm-up. Warm the hydraulic oil
sufficiently especially in winter or in the cold place.
- Especially in winter, the carrier's engine should be warmed up for 5 to 10 minutes 30~40℃(86∼105℉) before breaker
operation.
- When operating the hydraulic breaker, idle the engine and operate the hydraulic breaker with a light load.
[12] Stop operation when hoses are vibrating abnormally.
Check the hoses on the high pressure and low pressure sides of the breaker for abnormal vibration. If they are vibrating
abnormally, contact the nearest Soosan dealer.
[7] Do not operate breaker when all components except rod are immersed in water and mud.
Underwater usage of the breaker will cause internal damage to the breaker.
Consult Soosan for modifications if you have an underwater requirement.
[8] Do not allow the breaker to fall to a rock.
Falling down the breaker will apply excessive force to the breaker or the carrier, causing damage to the parts of the
breaker and carrier.
